On linear independence of integer shifts of compactly supported distributions
Linear independence of integer shifts of compactly supported functions plays an important role in approximation theory and wavelet analysis. In this note we provide a simple proof for two known characterizations of linear independence of integer shifts of a finite number of compactly supported distributions on R. By l(Z) we denote the space of all complex-valued sequences v = {v(k)}k∈Zd : Z → C...
متن کاملShearlet Coorbit Spaces: Compactly Supported Analyzing Shearlets, Traces and Embeddings
We show that compactly supported functions with sufficient smoothness and enough vanishing moments can serve as analyzing vectors for shearlet coorbit spaces. We use this approach to prove embedding theorems for subspaces of shearlet coorbit spaces resembling shearlets on the cone into Besov spaces. Furthermore, we show embedding relations of traces of these subspaces with respect to the real a...
متن کاملMagnetic Resonance Imaging Fusion by 3D Compactly Supported Shearlet Transform
T2* and quantitative susceptibility mapping (QSM) of magnetic resonance imaging (MRI) images provide different type inner structure information of scanned organs. If they can be properly fused into one set, the details of the scaned organ can be revealed more clearly. In this paper, a 3D MRI image fusion method based on 3D compactly supported shearlet transform (3D-CSST) and 3D dual tree compac...
متن کاملLinear Independence of the Integer Translates of Compactly Supported Distributions and Reenable Vectors
Some necessary and suucient conditions in time domain for the global and local linear independence of the integer translates of compactly supported distributions and reenable vectors are established in this paper.
متن کاملOptimally Sparse Approximations of Multivariate Functions Using Compactly Supported Shearlet Frames
In this paper, we introduce pyramid-adapted shearlet systems for the three-dimensional setting, and show how one can construct frames for L(R) with this particular shearlet structure. We then introduce a generalized three-dimensional cartoon-like image model class of piecewise C smooth functions with discontinuities on a C smooth surface with 1 < α ≤ 2 and show that pyramid-adapted shearlet sys...
